Surface dangling bond states and band-lineups in hydrogen-terminated Si, Ge, and Ge/Si nanowires
R. Kagimura, R. W. Nunes, H. Chacham
We report an ab initio study of the electronic properties of surface dangling-bond (SDB) states in hydrogen-terminated Si and Ge nanowires with diameters between 1 and 2 nm, Ge/Si…

Semiconducting chains of gold and silver
Frederico Fioravante, R. W. Nunes
The authors introduce a geometry for ultrathin Au and Ag wires that ab initio calculations indicate to be more stable than previously considered planar geometries for these systems…

Structures of Si and Ge nanowires in the sub-nanometer range
Ricardo Kagimura, Ricardo W. Nunes, Helio Chacham
We report an ab-initio investigation of several possible Si and Ge pristine nanowires with diameters between 0.5 and 1.2 nm. We considered nanowires based on the diamond structure,…
